Title: Loading and removal of carriers for catalysts etc. - e.g. in formaldehyde mfr., burning of ammonia, filtration (OE151176)
Inventor: MAYER FRIEDRICH DIPL ING
IPC: B01D46/30
Filed: 1975-11-21
Abstract: The carrier grids on which particulate solids such as catalysts, filter media or gas purificn. substances are held are placed in plates or boxes which can be pushed into and out of the plants in which they are used. The bed of solids can be replaced without shutting down the plant, thus output is increased, the quantity of residual reactants in a catalyst is reduced and the bed can be changed more frequently. The new bed can be preheated to the operating temp. before entering the process plant. Individual beds in a multiple-bed system can be changed.

Title: Printed circuits prodn. - of which the conductor lines have a flat angle at the base for integrated semiconductor circuits
Inventor: BADALEC RADIM
IPC: H05K3/14
Filed: 1976-01-29
Abstract: The parent patent describes the prodn. of microconductor lines on a substrate for integrated semiconductor circuits by masking an auxiliary coating having a defined pattern, etching the unmasked portion, coating the surface with the required material by vapour deposition and removing the auxiliary coating. The improvement is that the microconductor lines produced have a very flat angle at the base. This is achieved by applying an auxiliary coating with a thickness of 0.1-0.3 micron a light sensitive lacquer mask of 1-1.5 mu thickness and the line material by vapour deposition using an inclined angle to the surface of the support and a planet-vapour depositing unit, and for a period so as to give a line thickness of 1 mu.

Title: Plug connector for electrical appliances - has screened ventilation holes for contacts limiting contact temp. to 65 degrees C.
Inventor: FROEBEL ALFRED
IPC: H01R24/76
Filed: 1976-02-20
Abstract: The connector has contacts totally enclosed by the insulation body in order to give immunity against accidental touching of a live part, except of course the open end where the mating contacts enter. The necessary heat dissipation can be achieved by providing ventilation openings (10) in line with each contact. Each opening is provided with a baffle piece (13) and, on the inside of the baffle, the opening is constricted (12) by projections (11) in that part of the housing moulding. The layout of baffle and constriction is such that accidental contact with the live parts through the openings (10) is eliminated whilst at the same time giving direct access to cooling air.

Title: Pressure-tight capsule for introducing marking materials - for detecting leakage in fuel, fertile or absorber rods in nuclear reactor
Inventor: DREYER GERT
IPC: G21C17/04

Abstract: Pressure-tight capsule for introducing gaseous marking materials comprises a sleeve which can be closed by a lid which is fixed in the capsule opening by soft solder. The capsule is pref. lined up within the fuel, fertile or absorber rod in such a way that, when the solder melts, the lid falls out of the capsule opening under the action of gravity, thus releasing the opening. An outwardly projecting capillary tube which can be closed by melting pref. extends through the lid. The capsule opens automatically in operation of the rod, releasing the mixture of inert gases which becomes dispersed over the interior of the rod.

Title: Epicyclic gearing with stationary ring or sun gear - has brake action provided by increasing mesh of planet gears to cause friction
Inventor: SCHMEES GUENTER
IPC: F16H57/10
Filed: 1976-08-07
Abstract: Epicyclic gearing comprising a sun gear (4), a set of planet gears (3) and a stationary ring gear (2), has a brake comprising a second ring gear (8) meshing with toothed axial extensions of teh planet gears. The second ring gear is rotatable through a small angle e.g. by a lever. The rotation of the second gear causes interference as regards the meshing with the planet gears and the friction created in this way has a braking effect. If the gearing has a stationary sun gear, a like brake can be constructed by a second sun gear.
Patent DE-2638730-A1 (DE)
Title: N-channel storage FET with floating storage gate - has storage gate controlled channel bounding FET source with thin insulator in between
Inventor: MUELLER RUDOLF DR
IPC: G11C16/14
Filed: 1976-08-27
Abstract: The floating storage gate is surrounded on all sides by an insulator. The channel injection for charge reversal of the storage gate utilises the accelerated and heated electron in a conductive channel. Due to the heating by an electric field in the source-drain direction the electrons pass the energy threshold towards the conductivity band of the insulator to reach the storage gate. The channel injection is utilised for programmable charging of the storage gate. After charging the gate affects the source-drain path in a current restricting manner due to the negative charge. The channel region controlled by the storage gate (G1) bounds the source (S). Between the source facing storage gate region and the source proper the insulator (Is) is thinner than between the storage gate region and the channel and drain (D).

Title: Identification of replica of statues busts etc. - uses small permanent magnets moulded into replica that are detected by electric field
Inventor: VOSS GUNTHER
IPC: G09F3/00
Filed: 1976-09-16
Abstract: A means of identifying replicas of statues, coins from the originals incorporates the use of moulded-in magnets. Each replica is produced with a small permanent magnet moulded in a specific location. Detection is effected by subjecting the unit to an electrical field coupled to a meter. The need for such a technique is claimed, since many replicas are normally indistinguishable from the originals and it is becoming easier for forgers to copy object d'art.

Title: Boiler heating system temp. control system - has hot water ejected and cold water admitted to provide lower temps.
Inventor: LOTZ ROBERT DIPL ING
IPC: F24H9/20
Filed: 1977-03-25
Abstract: The boiler heating system has a temp. control preventing increase of temp. above a certain value. The boiler circuit temp. is monitored to ensure correct working temp. without interfering with the firing system, esp. in solid fuel boilers. In the vicinity of the boiler is arranged a temp. sensor. When the reference temp. is exceeded then the sensor operates a valve (5) by an actuating system (9). This valve allows escape of some hot water into the overflow. The sensor operates at the same time as the pipe separator (10) which allows flow of cold water from the supply mains until the temp. sensor reaches the lowermost temp.

Title: Vibration damper for low resonant frequency - is strip of plastics material of non-linear elasticity and high internal friction
Inventor: MUELLER GERHARD DR ING
IPC: F16F1/42
Filed: 1977-04-13
Abstract: The vibration damper of low resonant frequency is made of a plastics material having non-linear modulus of elasticity, high internal friction, i.e. high mechanical hysterisis, and a low plastic deformation. The material may have the shape of a flat section strip. The strip can be bent into U-shape for mounting between a static base and load-supporting flange. The resonance frequency may be altered by a change in the bending strength brought about by a change in the chemical composition of the material. Another way of changing the resonant frequency is by a change in the load having regard to the non-linear modulus of elasticity.
